Doubling the number of feedlines would double the losses. Not only that
but each connector in the system inserts losses so that number
would be 4x.

Increasing the coax diameter would effectively reduce the loss.

Matching the antenna won't make the Return Loss go away but it will make
the transmitter happy.

I use a short vertical antenna that has a low feedpoint impedance.

Would there be any advantage to running two parallel 50 ohm coax to
reduce losses to the shack tuner?
